WINDOW-SASH LOCK.

SPECIFICATION forming part of Letters Patent No. 775,524, dated November22, 1904.

Application filed May 31, 1904:. Serial No. 210,335. (No model.)

in the county of Cuyahoga and State of Ohio,

have invented certain new and useful Improvements in Window-Sash Locks;and I do declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to improvementsin window-sash locks; and theinvention consists in the construction of the lock substantially asshown and described,and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view of mysash-lock, shown as applied to two sections of the meeting-rails ofupper and lower sashes. Fig. 2 is a central cross-section of the lockand meeting-rails; and Fig. 3 is a plan View with the upper portions ofthe casing of the lock removed and showing the relation of the handle orlever thereto when it is engaged, as in full lines, and when the lock isopen, as in dotted lines. Fig. 4 is a perspective view of thelocking-bolt and its engaging member.

A represents the shell or casing of the lock adapted to be fastened uponthe top of the lower-sash meeting-rail A, and B represents the. engagedmember or keeper secured upon the meeting-rail B of the upper sash.

C represents the bolt, and D the controlling handle or lever engaged ina recess or slot 0 in said bolt and itself pivoted within the casing onpin or stud (Z. The said lever or handle D enters the casing or shell Athrough a slot in its side wall, in which said lever has room for thenecessary rotation, as shown in full and dotted lines, respectively, inFig. 3, and the locking position of the bolt and said lever or handle isshown in full lines in Fig. 3, while the open position of said parts isshown with the bolt back to permit the sashes to pass, as seen in dottedlines, Fig. 3.

The bolt C is designed to have a straight back-and-forth movement withinlimits in respect to the keeper B and is entirely clear thereof when itis withdrawn and adapted to slide back and forth in the casing A withinlimits, arear extension or stem 0 showing through-recess a in casingA atits rear, which serves as ajguide for the bolt at this point, while theforward portion of the bolt has fiat sides 2, resting against the walls3 of a recess in the casing. A spiral spring 4 about the shoulders 5 ofthe bolt and oppositely against the said stem or projection 0' bearsagainst the wall of the casing and serves normally to hold the bolt inlocking position;

The front portion of the bolt C has its opposite sides spaced apart, anda combined locking and liftingmember or book part Gr is pivoted betweenthe said sides 2 and has a hooked engaging portion 6, which is adaptedto engage beneath and behind the cross bar or rib 7 on keeper B. Thesaid hooked member G is further provided with a spur 8 at its topadapted to bear against the cross-rib 9 on the casing in the path of.the said spur, and the said spur and cross-rib have such relation toeach other and to pivot g when bolt C is carried inward for the purposeof locking that the said spur will impinge against rib 9 with its innerinclined surface and give a tilting turn or movement to the saidlockingmember G, causing it to both lift upward through its hook 6 on keepen?and-tilt to draw inward, and this operation has the effect of raisingthe upper sash and depressing the lower sash, if they have not alreadyreached their limits, and also of drawing the sashes closely together attheir meeting surfaces. A rear finger 10 on engaging member G serves asa stop or limit therefor in its tilting movement as it bears on the topof casing A, and it has'an inclined under side, deepest at the base ofthe finger, which causes the hook 6 to drop as the said member iswithdrawn and as said inclined portion bears against the end edge 12 ofthe top slot in the casing.

What I claim is- 1; In sash-locks, a casing and a sliding bolt a springat its rear to hold it in projected po-. sition, a handle-leverextending through the wall of said casing and having operating relationwith said bolt, and a tilting catch in said bolt, substantially asdescribed. 3. In a sash-lock, a casing and a sliding bolt therein, atilting catch mounted on said bolt having a hook at its outer end and aspur at its top, and the said casing provided with a rib in the path ofsaid spur, whereby when the bolt is closed the said spur will engage thesaid rib and raise the said hook, substantially as described.

at. In sash-locks, a casing and asliding bolt therein and a pivotedcatch in said bolt having a hook at its outer extremity, said catchhaving a spur at its top and a finger behindits pivot above said casing,substantially as described.

5. In sash-locks, a suitable casing, a sliding bolt therein and a leverto actuate said bolt,

and a tilting catch in said bolt provided with a hook atits outer end,in combination with a keeper constructed to be engaged by said hook frombeneath, substantially as described.

6. In sash-locks, a suitable casing, a sliding bolt therein and a springabout the rear portion of said bolt inside of said casing, acatchpivoted in said bolt having an upturned hook at its outer end and a spurabove its pivotpoint adapted to engage a portion of the said casing andthereby raise the said hook,in combination with a keeper having a ribadapted to be locked upon said hook, substantially as described.

I testimony whereof I sign this specification in the presence of twowitnesses.
